IMPRQVEMEN'T IN GALVANIC BATTERIES.

Specification forming part of Letters Patent No. 176,270, dated April 18, 1876; application filed February 19, 1876.

To all whom it may concern:

Be it known that I, GEORGE H. BLISS, of Chicago, in the count-y of Cook and State of Illinois, have invented a new and useful Improvementfin Galvani'c Batteries, `Which is fully described in the following speciication,

I referencebeing had to the accompanying drawings, in Which-- Figure 1 represents a vertical central 'sectional view ot' my battery; and Fig. 2, a transverse sectional v ieW taken at the line y y, Fi g. 1, leaving' the vertical stein H uncut.

This invention is made for the -purpose of enabling a ready adjustment of the parts in renewing the battery, and at the same time equalize the action of the battery and keep the sulphateV ofzinc'separate from the sulphate of copper. t

In theaccompanying,drawings, A- is the glass cup or cell: ofthe battery. B is the copperdisk, which ts into the cell and rests upon its bottoni. C is an insulated conducting-Wire, connected to the copper disk B, and D is a post securely attached to the center of the copper disk B. `E is` also a copper disk, nearly filling the `glass cup or cell A, and rests'upon the'post D, and is secured thereto by the set-screw F, which screws into the top -ot' the post D. G is a zncdisk, securely attach'ed to the stein H, and I is a -coverto the .glasscup or cell A. I stamp this cover, of the size to tit upon the top of the cup, out of sheet metal. There are holes J through this stem H, through--Which'a pin, K, passe-s, to hold the zinc disk suspended at any desirable height within the cell or cup of thebatte'ry L is a thu|nbscrew for attaching the wire to the stem H, and through it to the positive pole of the battery.

In charging the battery, the disk B, with its insulated wire and post attachment, is first placed in the cup A, and the blue-vitriol crystals placed upon this copper disk in such a\ quantity as maybe desired to make a charge; but Iordinarily fill the cup nearly or quite to the top ot' the post D. I then put the copper disk E in position and secure it on the top of this post by the screw F. The sulphate of zinc, in solution, isthen poured upon the disk E, and the zinc disk inserted and suspended from the cover by the pin K at the desired height. The sulphate of copper gradually passes up about the edges of the copper disk E, as required for the battery, and the action is more gradual and uniform on account of the separation produced by the disk E.

My battery is very simple and cheap, and

can be readily set up, and the adjustment of the zinc is readily made.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is-

l. The combination, in a galvanic battery, of the disk B, post D, and disk E, supported upon the post., as specified and shown.

2. The combination, in a galvanic battery, of the disks B and E, connected by a post, D, the zinc G, vthe zinc being suspended from the cover I and made adjustable, as specified and shown.
